How about Acoustat 1+1 speakers? I have had Acoustats, Audiostatics, Triangle, many horns, Lowthers, etc. The 1+1 remains one of my favorite. I just picked up another set a few months ago and am reminded why I love these so much. Part of the trick is my room, 8' wide X 14' long X 9' high. The bass is exceptional and the soundstage appears much bigger than the room should allow. And the amp I'm using has been even more surprising - a Cairn 30 watt class A integrated. I was unhappy with quite a few amps, and I threw this one in the mix. It doesn't go loud, but within it's power limits it's one sweet amplifier. My next move is to get the Cairn sound with more power, and I'm considering the Wyred for sound 500 W stereo amp.
Next up is a Triangle Zerius. Try it in a small room with a Red Wine ClariT and marvel at the huge involving sound. I have paid as little as $300 for a pair, and I can't think of a better used bargain. One consistent with all the speakers has been the Kimber 8TC. I can't find a speaker/amp combo that this doesn't click with.
